EI Core high-speed punch Lamination Scope:Power Transformer, Ballast ResistorUPS, Phone Charger<\/p>\n

Precision-Stamped Laminations for High-Efficiency Transformers<\/h2>\n

High-Speed Precision Punching<\/strong>
\nUsing high-speed progressive dies, EI laminations are stamped with superior edge finish and tight tolerances.<\/p>\n

Low Core Loss Silicon Steel<\/a><\/strong>
\nManufactured from cold-rolled grain-oriented (CRGO) or non-grain-oriented (CRNGO) silicon steel<\/a><\/p>\n

Optimized Lamination Stack<\/strong>
\nCarefully aligned E and I pieces reduce air gaps, minimizing magnetic resistance.<\/p>\n

Anti-Vibration & Noise Reduction<\/strong>
\nHigh flatness and even stacking reduce mechanical hum in transformer operation.<\/p>\n

Custom Hole Patterns & Coatings<\/strong>
\nOptional surface insulation coatings, mounting holes, and notching available upon request.<\/p>\n
